This command allows you to log active flows regularly. This solves the problem of

 

logging long-last active sessions as logs are normally generated only when a

 

session is established or deleted.

Example

# Configure the interval between sending NAT active-flow logs as 10 minutes.

 

<Sysname> system-view

 

[Sysname] nat log flow-active 10

 

# Delete the configured interval.

 

<Sysname> system-view

 

[Sysname] undo nat log flow-active

 

 

nat log flow-begin

 

Syntax

nat log flow-begin

Parameter

Description

Use the nat log flow-begincommand to generate NAT logs while establishing a

Use the undo nat log flow-begincommand to restore the default.

 

By default, no log is generated when establishing a session.

# Generate NAT log while establishing a session.

 

<Sysname> system-view
